the motion of the driving gear of the 1000- motive can be communicated to the cable reeling mechanism with the effect ofrotating the cable reeling mechanism always in the same direction irrespective of the direction of the travel of the locomotive, and also to provide in connection with the means for thus driving the cable reeling mechanism, suitable clutches and other controlling devices.

In the drawings, Figure 1 is av side elevation of a locomotive equipped with mechanism conforming to my invention. Fig. 2 is a. plan view of the locomotive. Fig. 3 is a vertical axial section of the cable reel and adjacent parts. Fig. l is a plan view of the mechanism for transmitting the motion of the driving gear to the cable reel. Fig. 5 is an end elevation of the transmitting mechanism. Fig. 6 is a section taken on the plane through the axes of the two counter shafts of the transmitting mechanism. Fig. 7 is a. cross sectional view taken along the line w-a0 of Fig. 6, with the clutches in the positions which they assume when the locomotive is moving in one direction. Fig. 8 is a view similar to Fig. 7 showing the clutches in the positions which they assume when the locomotive is moving in the other direction.

Gathering locomotives of the type shown in the drawings and described herein are used in mines to collect the loaded cars into trains from the rooms where the coal or ore is being mined and carry them to the mine shaft or the outside as the case may be. Be-

cause of the great expense of temporarily providing a trolley wire installation in the rooms themselves, a conductor cable is wound upon a reelcarried by the locomotive and the free end is secured to the trolley wire in the entry. When it desired to run are adaptedto be engaged by the-locomotive into one of the rooms or into a side entry unequipped with a trolley wire, the cable is paid out as the locomotive moves away from the trolley wire and is reeled up as the locomotive returns toward the trolley wire. The reels of such locomotives have been. actuated to wind up the cable in a number of different ways; by independent' electric motors, by power transmitting gearing connected to the motor for propelling the locomotive with the reel, by spring motors, etc. This invention relates to those locomotives in which the locomotive motor is also used to actuate the reel.

The frame of the locomotive comprising side castings 81-81, and the end castings 3232, is supported upon axles which rotate in boxes 34-34, and wheels 35 35, which are mounted in the usual manner uponthe axles. The motors 36-36 drive the axles, by means of the motor pinions 3737 and the spur gears 11 on the axles. The cable reel 45 is carried by a reel shaft 4:5- mounted in suitable hearings in the standards 45* on the frame of the locomotive, the reel being preferably rigidly secured to the shaft.

4:7 is a sprocket wheel loosely mounted on the shaft 45 and through which rotary motion may be imparted for rotating the cable reel 15. Preferably this sprocket wheel has formed integrally with it or secured to it i one element of a friction clutch t8, the other 1 element of which is movable relative thereto and is splined to the shaft 45.

48 are springs adapted normally to press the elements of the friction clutch into operative engagement with each other, and 4:9

isan operating device connected to the movable element on the clutch shaft 45. At the opposite end of the reel from this driving mechanism is arranged a friction retarding device indicated as an entirety by 50. This device is adapted to operate only during the paying off of the cable from the reel and preferably consists of a friction plate 50 carried by the reel and a cooperatingplate or disk 50 loosely mounted upon the shaft 4-5 and held normally in engagement with the plate 50 by the springs 50". The plate or disk 50 carries ratchet teeth 50 which a pawl 50 carried by an arm 425" secured to the adja cent standard 45. This pawl rides over the shaft 45, and is electrically connected to the electric collector at 51. From thence the current is conducted to the motors by the conductor 51;.

The reel, the mounting therefor and the,

immediately associated controlling mechanism therefor which I haveshown in the drawings have been selected merely for purpose of illustration and are not broadly claimed as part of my present invention.

Mounted in a suitable framework 17 at the reel end of the locomotive are two parallel transverse shafts 3 and 18. One of the shafts, preferably the upper one, 3, is rotatable and has secured to it the pinion 2, which meshes with one of the main driving gears 1. The shaft 3 is, therefore, rotated in one direction or the other whenever the locomotive is moved. Loosely mounted on the shaft 3 is a sleeve .3' andinterposed between this. sleeve and the-shaft is a bearing bushing 37*. Keyed to the sleeve 3' is a sec 0nd sleeveS, Upon this sleeve 8 is a hearing bushing 14 which has threaded engagement with the. sleeve and which is. held in place by the lock nut 15. A sprocket wheel 13 is. rotatably mounted onthe. bushing 14. This sprocket: wheel 13' is formed with an annular recess within which is mounted theinner toothed element 9 of a roller clutch 9. This inner element 9* is secured to the sleeve 8 by means of pins 11, At each side of the toothed element 9 is a flangelQ, the flanges serving to holdthe rollers 10 of the clutch in place. Also rotatably mounted on the sleeve 3 is a gear wheel 7, a bearing bushing 7 being interposed between. the gear wheel andthe sleeve. 4 is a clutch element splined to the shaft 3. A crank lever 5. and acontrol' rod6. are provided for moving the clutch element. This element, is provided with teeth and mating teeth 6 and 6? are provided on the gear .7 and on the sleeve 3 the construction being such that when the clutch element 4 is moved it may engage both the,

gear 7 and the sleeve 3 to cause. them to ro-. tate simultaneously.

It will be noted that by thev col1$12ruetion described I have provided two separate. clutches, one for connecting the gear wheel 7 with the shaft 3], and the. other for connecting the sleeve 3 with the shaft 3. r

The. shaft. 18. is held-against rotation and has rotatably mounted upon it a sleeve 18 to which is keyed a gear wheel 19 which'meshes with the gear wheel 7. The hub of the gear wheel 19 is extended and carries a bearin g bushing24 in threaded .engagement with it, a lock nut 25 being provided to hold the bearing bushing in place. Uponthis bearing bushing 24 is rotatably mounted a sprocket wheel 23 which is similar to and alines with the sprocket wheel 13. sprocket wheel 23 is provided with an annular recess within whichis mounted the inner element 21 of a roller clutch This inner clutch element 21 is secured to the gear wheel 19 by means ofpins 20, 20. At each side of the clutch element 21 is a flange 21 the flanges serving to hold the rollers 22 in place,

By referring to Figs. 1, 5, 7 and 8 it will be noted that when the locomotive is moving in the direction indicated by the arrow of Fig. 1, the shaft 3 will bedriven in the direction indicated by the arrow in Fig. 7 It being assumed that the clutch element 4 is in operative position, the rotation. of the shaft 3 in the direction indicated will cause the clutch 9. to operate to transmit motion in the same direction to .the sprocket wheel 13. From this sprocket. wheel 13 power is transmitted to rotate the reel in. the winding direction through the chain 16 which passes over the sprocket wheel 47 on the reel shaft and the two driving sprocket wheels 13and' 23. When the locomotive is. moved in the opposite direction, the direction of rotation of the shaft will also be reversed, as indicated in Fig. 8, and the clutch 9 will become inoperative. However, power. will be transmitted through the gears 7 and 19 to the clutch 21, which acts to rotate. thev sprocket.

wheel 23 in the direction indicated in Fig. 8. This sprocket wheel 23 causes the movement of the. chain. 16 and. the rotation of the sprocket wheel 47 in the same direction as before.

It will be understood from the foregoing description that by the arrangement of gears and clutches which I have. provided the reel driving sprocket wheel 47 is always rotated in the same direction, irrespective of the direction of motion of the locomotive. In.

other words, assuming the clutch 4 to. be. in operative position, whenever the locomotive isin motion the. sprocket wheel 47 is rotated in the direction to tend to wind the cable.

When the locomotive is moving away from the trolley wire the clutch 4 is thrown out of operative position.

manner and from unwinding the-cablefasterthan isnecessary-to lay it in a straight. line The The clutch 48. can be, allowed to remainin operative position and the friction brake 50will serve to maintain alongthe tracks. Under these circumstances the motion of the reel will be transmitted through the clutch 4L8, sprocket wheel 4:7 and chain 16 to the sprocket wheels 13 and 23, and since the clutch member'l is in its inoperative position, and there will be no tendency for the gears 7 and 19 torotate as the clutches 9 and 21 are inoperative for this direction of movement. WVhen, on the other hand, thelocomotive is moving toward the trolley wire, the clutch 4 is thrown into operative position, that is, into engagement with the jaws 6 6 on the sleeve 3 and gear 7, respectively, and the cable is wound upon the reel. The ratio of the gearing of the power transmitting mechanism is such that the axles tend to rotate the reel a little faster than is necessary to wind up the cable and the friction clutch 428 in taking care of this difference in the speed of rotation, will maintain sufficient tension in the cable'to hold it taut and insure its being wound uniformly and in a regular manner upon the reel and prevent it from forming loose folds upon the track and being run over by the locomotive wheels.

It will thus be seen that it is not necessary to operate-the clutch 48 at any time while the cable reeling mechanism is being used, but only to throw into and out of engagement the positive clutch member 4: as the locomotive is moving toward and away from the trolley wire, and it will also be evident that it matters not from which end of the locomotive the cable is being paid out, the entire cable reeling mechanism operating automatically to properly wind and unwind the cable under all circumstances, it being necessary for the operator merely to manipulate the clutch member 4.

Where the reel mounting is of a horizontal nature such as illustrated in the drawings, it is desirable that some sort of a cable spooling and guiding mechanism be provided for directing the cable onto the reel, and where such spooling and guiding mechanism is used, it is essential that it be adapted to operate to properly direct the cable on the reel irrespective of which end of the locomo tive is moving in advance toward the paid out cable. For this purpose I have provided a cable spooling and guiding mechanism which is indicated as an entirety by 64. Of this mechanism 64:, 64* indicate arms loosely mounted upon the reel shaft 45, each one preferably being adjacent to one of the standards 45 At their outer ends each of these arms carries a bearing block or plate 64L".

65 is a double threaded shaft arranged parallel to the reel shaft 45- and mounted at its ends in bearings in the adjacent bearing blocks 64: At the friction clutch end of the reel the shaft65 has secured to it a sprocket wheel 66. 1

When the cable is to be paid off from and wound onto the reel at the reel end of the locomotive, it is desirable to have the cable spooling and guiding mechanism arranged as shown in dotted lines'in Fig. 1, so that the traveler 69 for guiding the cable onto the reel will'be in front of the reel. To hold the cable spooling and guiding mechanism in this position I have provided brackets 33 arranged at either side of the reel supporting structure, each secured to an adjacent standard 45 and each adapted to engage with and support one of the bearing blocks 64".

When it is necessary to pay out and reel up the cable from the operators end of the locomotive, the cable spooling and guiding mechanism may be swung to the position indicated in full lines in Fig. 1, in which case the cable guiding traveler is still in front of thereel when the direction of travel of the reel is considered. For maintaining the spooling and guiding mechanism in this position I have provided brackets 83* each arranged at one end of the reel supporting frame, each secured to the adjacent standard 4:5 and each adapted to engage and support one of the bearing blocks 64?.

The transversely arranged guide and supporting rollers carried by the traveler 69 are so arranged that one of them will support the flexible cable when the spooling and guiding mechanism is in one position while the other will support the cable when the said mechanism is in its other position.
